Cupro MAX (CuCrZr) Hard Copper Alloy

Cupro MAX (CuCrZr)

Cupro Max (CuCrZr) is one of the copper alloys with the highest electrical conductivity. Because it is alloyed with chromium and zirconium, its hardness is higher than pure copper, and it can also be shaped by wire erosion.

What is Cupro Max (CuCrZr) Material?

What are the Properties of Cupro Max (CuCrZr)?

The heat and electrical conductivity of copper alloys decrease as the hardness increases. Cupro Max (CuCrZr) has 2 times higher hardness than pure copper without losing much of its electrical conductivity. For this reason, it is used in places where both hot and cold abrasion resistance and conductivity are expected. As an EDM electrode, it shows 3 times more wear resistance than pure copper in the plunge erosion process.

Where is Cupro Max (CuCrZr) Used?

Cupro Max (CuCrZr); Electrode tips and discs of low carbon steels and galvanized sheets in resistance welding, continuous casting molds of steel and aluminum, electrodes of plunge electro-erosion machines, cooling parts and molds in the casting of non-ferrous metals, pistons of aluminum injection machines, welding and seam ends in plastic packaging, plastic injection machines It is used in spray nozzles, as cathode carrier and guide plate in Galvano technique, in electrical equipment, contacts, studs, connection bars, forming and cooling tools in plastic extrusion.

It is used in contact rings of asynchronous motors of electric vehicles and renewable energy sources in new generation applications.

What is the Price of Cupro Max (CuCrZr) Material?
